Make desktop visible while Photoshop is in use (Windows) - Add "desktop" as Application Frame option?

It would be great if Photoshop CS6 for Windows had the option (as older versions had) to get rid of the grey (default) background so that the desktop could be viewed while a document is up (or down for that matter, but with the Photoshop tool bars and menu visible - like on the Mac. I think this feature is called the Application Frame? All questions about this have lead me to right click on the background and I'm given the option to change the background to default, grey, black, or custom but it would be great to have a "hide" or "desktop" option in that list! Here's an image of someone else who had the same problem:

Is there an update already? Just as a side note - I'm an Illustration Major studying at an art school who has provided a "student" version of CS6 creative suite - in any case, it would be nice if this feature was in all versions of Photoshop!
Anyway I'll be getting the newest version of Photoshop after I graduate, and I'm hoping this feature has been added to speed up my illustration work!
Thank you!
